        **Instructions:**
        
        1. Log in to your Hugging Face account using the button below.
        2. Click 'Run Evaluation & Submit All Answers' to fetch questions, run your agent, submit answers, and see the score.
        
        **Configuration:**
        
        You can configure the agent by setting these environment variables:
        - `AGENT_MODEL_TYPE`: Model type (HfApiModel, InferenceClientModel, LiteLLMModel, OpenAIServerModel)
        - `AGENT_MODEL_ID`: Model ID
        - `AGENT_TEMPERATURE`: Temperature for generation (0.0-1.0)
        - `AGENT_EXECUTOR_TYPE`: Type of executor ('local' or 'e2b')
        - `AGENT_VERBOSE`: Enable verbose logging (true/false)
        - `AGENT_API_BASE`: Base URL for API calls (for OpenAIServerModel)
        
        **xAI Support:**
        - `XAI_API_KEY`: Your xAI API key
        - `XAI_API_BASE`: Base URL for xAI API (default: https://api.groq.com/openai/v1)
        - When using xAI, set AGENT_MODEL_TYPE=OpenAIServerModel and AGENT_MODEL_ID=mixtral-8x7b-32768
        
        **InferenceClientModel specific settings:**
        - `AGENT_PROVIDER`: Provider for InferenceClientModel (e.g., "hf-inference") 
        - `AGENT_TIMEOUT`: Timeout in seconds for API calls
